Updates to the Colemak-DH keyboard layouts in FreeBSD
- Rename from Colemak Mod-DH (the project name) to Colemak-DH (the layout name)
- Split keyboard layout into the two main variations: Colemak-DH (for ANSI keyboards) and Colemak-DH ISO (for ISO keyboards).
The naming is consistent with how it's done in XKB.
